TENSION DEVICE.

To all whom it may concern.- I

Be it known that I WILLIAM J. RHODES, a citizen of the United tates, residing at Elizabeth, in the county of Harrison and State of Indiana, have invented certain new and useful Improvements in Tension Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same.

My invention relates to tension devices for binders; and its object is to provide a simple, durable, and com act device of this character which will ho d cord under tension, said tension being capable of adjustment.

A still further object is to provide a novel form of s 001 on which the cord is mounted, said spoo being formed of sections which are ada ted to clamp the cord.

ith the above and other ob'ects in View the invention consists of a brac et in which is mounted a stem havin a plate slidably supported thereby, said plate being spring pressed and contacting with the sliding memer of a sectional spool, which is located on the stem between the bracket and plate. All portions of the spool rotate in unison upon the stem, but are at the same time capable of lateral adjustment. a

The invention also consists in further novel construction and combination of arts, hereinafter more fully described and c aimed.

In the accompanying drawings I have shown the preferred form of my invention, and in said drawings- Figure 1 is a perspective view of the tension deviceand showing acord en aging the same. Fig. 2 is a section through t e tension device. Fig. 3 is a section through the main member of the spool, and Fig. 4 is an inner c elevation of the other member thereof.

' Referring to the figures by numerals of ref-. erence, 1 is a stem having a head 2, which is preferably angular and provided with a second stem 3, which is adapted to engage any suitable support, so that the tension device Specification of Letters Patent.

is mounted on the stem 1 and bears at one end against the enlarged portion of the crossbar, while its other end contacts with the nut 11, threaded on the stem.

Rotatably mounted on the stem and contacting with the bracket 6 is the main member 12 of the spool. This member has a tubular extension 13 at the center thereof, which surrounds the stem 1 and has grooves 14 therein. A disk-like member 15 constitutes the other section of the spool, and this member is mounted on the tubular extension 13 and has lu s 16, which fit within the grooves 14, so t at the two members 12and 15 must necessarily rotate together; but said member 15 is at the same time capable of moving longitudinally of the extension 13.

As heretofore stated, the member 12 contacts with bracket 6. The member 15 contacts with the cross-bar 8, and as this bar is spring-pressed it will be obvious that the two s ool-sections' are normally pres'sed together.

he tension of the spring 10 can be regulated by means of the nut 11. Ears 17 extend from the upper end of bracket 6 and have spools 18, ournaled therebetween, these spools being disposed upon op osite edges of said end. The cord 19 is a apted to pass over one of the spools 17 and down between the spool-sections 12 and 15 and then around the extension 13 of section 12 and up over the other s 001 18.

. It will 0 course be understood that when the cord is drawn between the spool-sections 12 and 15 it will force them apart and increase the tension of spring 10, and therefore the cord will be tightly clamped between the i will be retarded in its spool-sections an The bracket 6 movement therebetween.

and the cross-bar 8 serve to retard the rotastead contacts at all times with the s ool-sections only, and the extension 13 oft e spoolsection 12 relieves the stem of all wear.

Either or both of the sections of the spool can be quickly replaced should they become worn or broken, and as the device is ver simple and compact in construction it will e found .ve desirable for use upon binders.

aving thus fully described my invention,

no i

what I claim as new, and desire to secure by Letters Patent, is

1. A tension device of the character described, comprisin 4 a stem, a non-rotatable bracket mounted t ereon, a cross-bar engaging the bracket and slidably mounted on the stem, a spool-section rotatably mounted on the stem and havin a grooved tubular extension, anotherspoo -sectionslidablymounted on the extension and rotatable therewith, both of the spool-sections being interposed between and contacted by the bracket and cross-bar, and tensioning means contacting with and adapted to actuate'the cross-bar.

2. A tension device com rising a stem, a bracket fixedl mounted t ereon, a springpressed cross-liar slidably mounted on the stern and engaging the bracket, and a sectional spool interposed between the bracket and cross-bar, one of said sections constituting a support for the other section and said sections being normall clamped together bv the bracket and crossan 3. A tension device comprising a stern, a

bracket fixedly connected thereto and havln guide-spools thereon, a cross-bar slid ably mounted on the stem and engaging the bracket, a tension-spring u on the stem and bearing on the cross-bar an a sectional spool rotatably mounted on the stern and interposed between the bracket and cross-bar, one of the sections of the spool being slidably mounted on, but rotatable with the other section and both sections being normally clamped together by the bracket and cross-bar. I

In testimony whereof I have signed my name to this specification inthe presence of two subscribing witnesses.
